public lineTo(x:Number, y:Number) : Void
Draws a line using the current line style from the current drawing position to (x, y); the current drawing position is then set to (x, y). If the movie clip that you are drawing in contains content that was created with the Flash drawing tools, calls to lineTo() are drawn underneath the content. If you call lineTo() before any calls to the moveTo() method, the current drawing position defaults to (0,0). If any of the parameters are missing, this method fails and the current drawing position is not changed.
You can extend the methods and event handlers of the MovieClip class by creating a subclass.
x:Number - An integer indicating the horizontal position relative to the registration point of the parent movie clip.
y:Number - An integer indicating the vertical position relative to the registration point of the parent movie clip.
The following example draws a triangle with a 5-pixel, solid magenta line and a p artially transparent blue fill:
this.createEmptyMovieClip("triangle_mc", 1);
triangle_mc.beginFill(0x0000FF, 30);
triangle_mc.lineStyle(5, 0xFF00FF, 100);
triangle_mc.moveTo(200, 200);
triangle_mc.lineTo(300, 300);
triangle_mc.lineTo(100, 300);
triangle_mc.lineTo(200, 200);
triangle_mc.endFill();
beginFill (MovieClip.beginFill method), createEmptyMovieClip (MovieClip.createEmptyMovieClip method), endFill (MovieClip.endFill method), lineStyle (MovieClip.lineStyle method), moveTo (MovieClip.moveTo method)
